Network Optimization Models Allocating demand to production facilities Locating facilities and allocating capacity Key Costs: Fixed facility cost Transportation cost Production cost Inventory cost Coordination cost Notes: Which plants to establish? How to configure the network? 5-4
Gravity Methods for Location Ton Mile-Center Solution x,y: Warehouse Coordinates xn, yn : Coordinates of delivery location n dn : Distance to delivery location n Dn : Annual tonnage to delivery location n Fn: cost of shipping one unit for one mile to location n Notes: Min 5-5
Demand Allocation Model Which market is served by which plant? Which supply sources are used by a plant? xij = Quantity shipped from plant site i to customer j 5-6
Plant Location with Multiple Sourcing yi = 1 if plant is located at site i, 0 otherwise xij = Quantity shipped from plant site i to customer j Notes: 5-7
Plant Location with Single Sourcing yi = 1 if plant is located at site i, 0 otherwise xij = 1 if market j is supplied by factory i, 0 otherwise Notes: 5-8
